Long time since I've posted on here. Anyways, I've got a 95 3.4 maro, t5. For a month or so now it's been idling high(around 2k rpm) when I first crank it, everytime; also just after i take it out of gear to stop at a light. Wierd thing is I can tap the gas pedal(just touch it, not enough to rev it at all) and it will always go back to normal idle(1k) The only thing I know of that's really wrong with the engine is my crankshaft position sensor is broken, and kind of dangling(has been for a few months before this problem though) and I have a new one, just been too caught up in other stuff to put it on. Any ideas?

Thanks,
Lynn

 

my old 95, 3.4 used to have a slightly iffy idle when i first started, so i took out the IAC sensor (on the side of the throttle body, poisitioned slightly above, check your haynes manual), and cleaned it, that fixed it for me... hope this helps

I forgot to mention that I put in a new iac just after it started doing this, no change. thanks

 

pull the PCM fuse , put it back in , start the car... let it run 5 min .. turn it off, wait 5 min, turn it on again.. should reset itself.. turn it off then you should be ready to roll

 

did that a couple times too.....guess I should've mentioned the stuff I've already tried to correct it
